Non-enzymatic electrochemical glucose sensor based on NiMoO 4 nanorods

A non-enzymatic glucose sensor based on the NiMoO 4 nanorods has been fabricated for the first time. The electrocatalytic performance of the NiMoO 4 nanorods’ modified electrode toward glucose oxidation was evaluated by cyclic voltammetry and amperometry. The NiMoO 4 nanorods’ modified electrode showed a greatly enhanced electrocatalytic property toward glucose oxidation, as well as an excellent anti-interference and a good stability. Impressively, good accuracy and high precision for detecting glucose concentration in human serum samples were obtained. These excellent sensing properties, combined with good reproducibility and low cost, indicate that NiMoO 4 nanorods are a promising candidate for non-enzymatic glucose sensors.
